I have got black circles that have appeared on my screen with a white halo about the the size of my finger tip. They flicker on and off near the bottom of the screen and get worse the longer the PC is on. When this happens I can't use it. Never had this problem before. Any help would be appreciated. Cheers.
Thank you for posting on HP Support Forums. It is a great place to find the help you need, from other users, HP experts, and other support personnel. I see from the post that you are having issues with the screen on your HP Envy All-in-one PC. Don't worry as I have a few steps to help you get through this concern,
To provide you with an accurate solution, I'll need a few more details:
Have you made any changes on the PC before the issue started?
Was there any update/reset interrupted recently?
Have you tried to update the drivers?
In the meantime, let's start off by performing a Hard reset on the PC with all the cables disconnected:
Step 1: Performing a hard reset
Many startup errors and other problems can be resolved by decreasing the amount of power stored in hardware components. Decreasing stored power is sometimes referred to as a "Hard Reset." Use the following steps to perform a hard reset on a computer:
Turn off the computer completely; disconnect the power cord from the back of the computer.
With the power off and the power cord disconnected, press the power button on the computer for 5 seconds. The power light indicator on or near the power button might turn on briefly but then go out.
Reconnect the power cord and turn on the power.
Step 2: Boot the computer into the Bios screen and check if you see black circles with a white spot.
1. Turn off your computer
2. Make sure you have connected the power cable
3. Turn on your notebook, as it is starting press the F10 button repeatedly
Once you are in the BIOS, if the screen has black circles with the white spot, it is likely a hardware failure. The next two steps may resolve the issue. The first one is to do a hard reset. I have included the steps. The next and final step is to perform a BIOS update. I have included the information here for you 'Updating the BIOS' as well as updating the graphics card drivers from our HP Support website, using this link.
Please respond to this post with the details and the result of the troubleshooting for further assistance.
